Python uses Jsonscheme to reference ref error unknown URL Type:definitions.json

Problem

Put definitions in the current document, no problem, put in an external file, according to the official document description:

main.py file

from jsonschema import validatea = {    "type": "object",    "required": ["shipping_address"],    "properties": {        "shipping_address": {"$ref": "definitions.json#/address"}    }}ins = {"billing_address": 1, "shipping_address": 2}validate(ins, a)

Definitions.json file

{  "Adress": {      "Type": "Object",      "Properties": {          "Street_address": {"Type": "string"},          "City": {"Type": "string"},          "State": {"Type": "string"}    },    "Required": ["Street_address", "City", "State"]}}

Resolve the use of file

main.py file

fromimport= {    "type""object",    "required": ["shipping_address"],    "properties": {        "shipping_address": {"$ref""file:address.json"}    = {"billing_address"1"shipping_address"2}validate(ins, a)

The file here uses a relative path relative to the current running directory.

Address.json file

{    "Type": "Object",    "Properties": {      "Street_address": {"Type": "string"},      "City": {"Type": "string"},      "State": {"Type": "string"}    },    "Required": ["Street_address", "City", "State"]  }

Here a definition is required to write a separate file, and for the moment there are no references to multiple definition writes to a JSON file.
